Left is idle, right is under full gaming load (Helldivers 2). My previous rig (Intel) easily went up to 85-90°C in the same circumstances. Ambient temps are slightly elevated as well since we've been having ~30°C temps daily here for a while now.
To me this is almost ridiculous. I had never dreamed I could get my temps under load under 70. CPU is at stock speed since there is literally no reason to push it any further at this point. Can always choose to up the clocks later if I still want to.
Cooler is a Noctua NH-D15 G2. I don't see myself returning to watercooling any time soon. And Noctua has a new customer for life.
Pump should be at 100% all the time anyway
